Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aimed to compare the effectiveness of virtual reality (VR) and vestibular rehabilitation therapy (VRT) in enhancing balance in individuals with Persistent Postural-Perceptual Dizziness (PPPD). The experimental group received VR combined with VRT and optokinetic stimulation, while the control group received VRT and optokinetic stimulation. The study involved 42 individuals diagnosed with PPPD and administered ten intervention sessions over six weeks. The study also examined the impact of VR on various aspects of PPPD, including dizziness, visual vertigo, mental well-being, sleep quality, fall risk, and overall quality of life.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Persistent Postural-Perceptual Dizziness (PPPD) represents a relatively new vestibular diagnosis that has garnered recent attention within the medical community. Consequently, there exists a pressing demand for efficacious and innovative management strategies. The primary purpose of this study was to assess the comparative effectiveness of virtual reality (VR) versus vestibular rehabilitation therapy (VRT) in enhancing balance among individuals afflicted with PPPD. A secondary purpose encompassed an investigation of VR's impact on various dimensions of PPPD, including dizziness, visual vertigo, mental well-being, sleep quality, fall risk, and overall quality of life. Materials and Methods: A cohort comprising forty-two individuals conclusively diagnosed with PPPD was randomly assigned to two distinct groups. The experimental cohort comprised twenty-one participants subjected to a combination of VR with optokinetic stimulation alongside VRT, whereas the control group, also consisting of twenty-one individuals, underwent solely optokinetic stimulation paired with VRT. The intervention sessions were administered twice weekly over a span of six weeks, resulting in a total of ten intervention sessions. Additionally, baseline and post-intervention assessments were conducted to gauge the efficacy of the interventions.

Vestibular Rehabilitation Therapy (VRT)

Participants went through conventional VRT in addition to optokinetic exercise training. The VRT exercises were composed of gaze stabilization, head motion, and postural stability exercises with static and dynamic balance exercises. Ten repetitions of each VRT exercise were practiced in the same session for three sets. Moreover, participants were instructed to watch optokinetic stimulation videos. The optokinetic stimulation training was conducted using the following displays (a mobile and TV screen).

Group Type ACTIVE_COMPARATOR

Vestibular Rehabilitation Therapy (VRT)

Intervention Type OTHER

The VRT exercises were composed of gaze stabilization, head motion and postural stability exercises with static and dynamic balance exercises.

Optokinetic Stimulation exercises

Intervention Type OTHER

Optokinetic Stimulation is a type of visual stimulation used to improve visual function and balance in patients with vestibular disorders.

Virtual Reality

The same intervention program for the control group was implemented for participants in the experimental group, with the addition of using the VR split screen in Samsung Gear VR goggles in the last 4 sessions. Using the VR goggles, participants started watching the videos for 30 seconds to 1 minute in the sitting position in the first two sessions, followed by 1-2 minutes in the standing position for the last 2 sessions.
